The main signs your central heating needs a powerflush are radiators cold at the bottom, radiators that need frequent bleeding, discoloured water, noisy boilers or pipes, some rooms staying colder than others and a system that is slow to warm up. A powerflush from PropertyHeat typically costs £400 to £1,500.
A heating system that used to work well can slowly get worse, and it is easy to get used to it. Sludge and debris in the system are a common cause. Here are the signs to look for, and how to tell whether a powerflush is worth doing.
The 6 Signs to Look For
- Radiators cold at the bottom: Hot at the top and cold at the bottom often points to sludge sitting in the radiator.
- Frequent bleeding: If you are always bleeding the same radiators, something is not right.
- Discoloured water: Dark water when you bleed a radiator can be a sign of debris in the system.
- Noisy boilers or pipes: Banging, gurgling or rumbling can mean water is not moving freely.
- Some rooms colder than others: If one room never gets warm, the flow may be restricted.
- Slow to warm up: A system that takes a long time to get going may be struggling to circulate.
What a Powerflush Does
A powerflush uses a dedicated pump, connected to your heating system, to push water through the pipes and radiators and shift the build-up. The dirty water is then drained away, leaving cleaner water moving through the system.
What It Costs
A powerflush from PropertyHeat typically costs £400 to £1,500, depending on the size and condition of your system. You will get a clear quote before any work starts.
When It Is Not the Answer
These signs do not always mean you need a powerflush. A cold radiator can have other causes, and a noisy boiler may have a fault that needs a repair instead. We look at the symptoms and the system first, and we will tell you honestly if a powerflush is not going to fix it.
